And there could've been more (we've spared you, 'Dance Flick,''Bride Wars,' and 'Ghosts of Girlfriends Past'). It's with deep regret that we present the very existence of these 10 clunkers.
You know what's funny? Not many of the comedies that were released in 2009, that's for sure.

10. 'I Love You, Beth Cooper'
Since we couldn't possibly do justice to the vitriol of the reviews for this teen comedy starring Hayden Panettiere, we'll let our friends in the critical community sum it up. Ben Lyons: "This is a pathetic excuse for a movie." Variety's Brian Lowry: "'Beth Cooper' peaks early -- like, during the first three minutes -- and rapidly goes downhill from there." Film.com's Eric D. Sneider: "(It) wants to emulate a John Hughes film, in much the same way that a crack whore wearing a dime-store tiara wants to emulate Queen Elizabeth." -- Kevin Polowy

Watch the Trailer | Rotten Tomatoes Rating9. 'Couples Retreat'
Man did we pine for the days of "beautiful babies" and being "so money" watching this dreadful flick with Vince Vaughn and Jon Favreau. With a boring, run-of-the-mill plot involving four couples stranded on an island and forced into couples therapy (snore!), we knew not to expect 'Swingers'-quality genius. But we also didn't think co-writers Vaughn and Favreau could be so off target. The laughs come sparingly (if at all) and the script is about as predictable as sunset. -- Alicia Roda

Watch the Trailer | Rotten Tomatoes Rating8. 'Whiteout'Kate Beckinsale is a U.S. Marshall, tracking a killer in Antarctica. Unbelievable? Absolutely. Then came the "We're about to be stranded with a killer and no sun for months!" The South Pole twist sealed the fate of this clunky, um, thriller. But I guess if you call losing a finger to frostbite, chase scenes almost completely shrouded by snow and a bad guy with the last name (spoiler!) Fury thrilling, then this is your flick. -- Maggie Furlong

Watch the Trailer | Rotten Tomatoes Rating7. 'Land of the Lost'
Blending action and comedy is never a safe bet. Adapting a beloved TV show for the big screen is even dicier. This Will Ferrell-fied take on the Sid and Marty Krofft classic now qualifies as new evidence against in both of those categories. Other lessons Hollywood can learn: Avoid jokes that revolve around monkeys sexually harassing female humans, dinosaur urine showers and getting pooped out of a T-Rex. -- KP

Watch the Trailer | Rotten Tomatoes Rating6. 'The Ugly Truth'Katherine Heigl plays another uptight career woman who eventually lets her hair down for another he's-so-wrong-but-so-right-for-you playboy (Gerard Butler) in yet another cliched romantic comedy that lacks any reality. The ending could be spotted from the trailer, and the absence of chemistry between Heigl and Butler makes the 95-minute journey to it all the more painful. And that's the ugly truth. -- Andy Scott

Watch the Trailer | Rotten Tomatoes Rating4. 'Old Dogs'
Again, we'll refer to the critical community for the most colorful insight on this dog with Robin Williams and John Travolta. The Boston Globe's Ty Burr: "If 'Old Dogs' isn't the absolute worst movie either star has appeared in, it's close enough to count." The New York Post's Kyle Smith: "Old Dogs does to the screen what old dogs do to the carpet." Reelviews' James Berardinelli: "There are some experiences no one should be subjected to even in the name of science. It may be that forced viewing of this film has been outlawed by the Geneva Convention." -- KP

Watch the Trailer | Rotten Tomatoes Rating3. 'Year One'
Think the short-lived 'Caveman' TV show was the unfunniest portrayal of prehistoric humans ever produced? You're very wrong. Former 'Ghostbuster' Harold Ramis misses horribly with this primitive bromance that thinks its viewers will be astute enough to follow all the Biblical references yet juvenile (or stoned?) enough to giggle at the sight of an upside down Michael Cera urinating into his own mouth. -- KP

Watch the Trailer | Rotten Tomatoes Rating2. 'All About Steve'
Moviemaking rule #29: Never turn America's sweetheart into a chemically imbalanced stalker with a speech impediment. That should be a given, but 'All About Steve' -- Sandra Bullock'sother 2009 flick -- was all about breaking those rules. Also misused: Bradley Cooper (with bleach blond tips!), Thomas Hayden Church and Ken Jeong (it's hard to make him unfunny). The only one who belonged in this highly uncomfortable "comedy" was DJ Qualls. (Yes, that DJ Qualls.) -- MF

Watch the Trailer | Rotten Tomatoes Rating1. 'Miss March'
We know they can be funny -- we've seen 'Whitest Kids U Know.' But there's just no excuse for this waste starring Zach Cregger (here duller than dull) and Trevor Moore (like a Matthew Lillard lookalike imitating Jim Carrey). We're not sure which is worse: that 'Miss March' plays like a 90-minute advertisement for Playboy, or that it's a painfully, painfully unfunny 90-minute advertisement for Playboy. But we're sure they had fun making it. -- KP
